This invention relates generally'to improvements 1n Wheels ofpressed construction, and also particularlyrelatesto a heel, ofethis-type, formed of two parts respectively a-rim and, a hub section, ,s ecured; together by suitable fasteningdevices, and providing .a continuousabutting relation-of the parts to .holdthem against movement in adirectioniperpendicularly to thejaxis of rotation.

Another object is to provide a construction in which the load is transferred from 'a pressed steel rim d rectly instead otthrough j boltsor rivets or other fastening devices;

' One of the 'featuresinclndes'the'use'of fastening devices merelyto hold the parts together in an "axial direction, and not in a direction perpendicular to the axis of rotation. Thus less accuracy is required in drille iameter-of these openings iscsometvhat greater than. he diameter'of the shanksiof the fastening devices.

7: The, invention herein is shown applied-to a com'n1 on form of pressed steel motor car wheel; It will-be understood that intheordinary constructions the-fastening devices act to secure the parts against-"movement both in an axial dir'ection'and'in'direction'perpendic ular to the axis of rotation. An important" feature: of this invention is-to abuttinglyarrange the rinifand-the hub in such a manner as to increase the area flof contact circumfer. entially, and make it continuous, and to -ha v'e the abutting parts only co-act-to carr y- 'the entire'vertical load. f

" This invention is an improvement over my prior patents, respectively numbered-1,61 5,-

f709and-Reissue No'.-16,520. ,One ofthe main ifeatures herein, diflering from those shown inthe patents n1entioned,is the increasing ofthe area of abutting. contact between the hub and the rim, and at the same time; retain- ,ling all the advantagesjo'f. the construction shown in the patentsreferredto.

This is also a feature but there isno inten-' tionto be limited to the-particular'kind of fastening device or the manner of applying, the invention broadly consisting of abuttingly engaging the wheel and hub and providing a substantially large area of engage merit for the purpose set forth.
